Researchers studying the relationship between honesty, age, and self-control conducted an experiment on 160 children between the

ages of 5 and 15. The researchers asked each child to toss a fair coin in private and to record the outcome (white or black) on a paper sheet, and said they would only reward children who report white. Half the students were explicitly told not to cheat and the others were not given any explicit instructions. Differences were observed in the cheating rates in the instruction and no instruction groups, as well as some differences across children's characteristics within each group.

Answer:

The population of interest in this study is:

children between the ages of 5 and 15.

Step-by-step explanation:

In research methodology, the population of interest is the comprehensive group of individuals, institutions, objects, and so forth who possess some common characteristics that are the interest of the researchers.  In our example, the researchers are studying the relationship between honesty, age, and self-control. The common characteristic of the group in this case is the age group between the ages of 5 and 15.  This characteristic distinguishes the children of this age group from other individuals, institutions, objects, and so forth.

what is the general form for a number written in scientific notation? what are its practical applications?
patriot [66]
The general form for a number written in scientific notation would be a x 10^n. <span> where a must be between 1 and 10, and n must be an integer. This type of form is useful when dealing with very large numbers or very small numbers. Hope this answers the question. Have a nice day.</span>

Answer:

width = 8 feet and length = 12 feet

Step-by-step explanation:

Let the width be w then the length = 3w - 12 ( 12 less than 3 times the width )

The area (A) of a rectangle is

A = length × width, that is

w(3w - 12) = 96 ← area of floor

3w² - 12w = 96 ( subtract 96 from both sides )

3w² - 12w - 96 = 0 ← in standard form for a quadratic equation

Divide all terms by 3

w² - 4w - 32 = 0

Consider the product of the factors of the constant term ( - 32) which sum to give the coefficient of the w- term (- 4)

The factors are - 8 and + 4, since

- 8 × 4 = - 32 and - 8 + 4 = - 4, hence

(w - 8)(w + 4) = 0

Equate each factor to zero and solve for w

w - 8 = 0 ⇒ w = 8

w + 4 = 0 ⇒ w = - 4

However, w > 0 ⇒ w = 8

Hence width = 8 feet

length = 3w - 12 = (3 × 8) - 12 = 24 - 12 = 12 feet

The graph of the solution to this inequality is: C. number line with an open circle plotted at negative eight and arrow pointing left.

<h3>What is a number line?</h3>

A number line simply refers to a type of graph with a graduated straight line which contains both positive and negative numbers (numerical values) that are placed at equal intervals along its length.

Next, we would solve the given inequality as follows:

−0.4b + 2.4 < 5.6

Subtracting 2.4 from both sides, we have:

−0.4b + 2.4 - 2.4 < 5.6 - 2.4

−0.4b < 5.6 - 2.4

−0.4b < 3.2

Dividing both sides by -0.4, we have:

b < -3.2/0.4

b < -8

In conclusion, the circle on a number line should be open and would point to the left when the inequality symbol is <.
